4. Troubleshooting
Situation Solution
The activated lens fi le does not
correspond with the lens mounted
on the projector.
Activate a lens fi le which does correspond with the mounted lens or mount an other lens
which corresponds with the lens fi le you want to activate.
Corrupt lens fi le. Delete the lens fi le and program correct lens type into communicator under
Advanced/lens parameters and recreate a new lens fi le. Tip: perform a “Lens Homing”
before creating a new lens fi le. Otherwise, if the lens is removed the existing lens fi le
becomes useless. Setup all new lens fi les away from the maximum limitation of the lens
zoom. It is possible that the lens fi le was originally created at the maximum or minimum
zoom capabilities of the lens zoom.
The fi nal lens position lays very
close to the mechanical limits which
disable the motorized lens position.
Position the lens manually, or reposition the projector so that the lens position lies further
away from the mechanical limits, or try to use another lens which range is more suitable.

Disconnected wire units (reference
1 image 4-19) of the zoom motor of
the motorized lens. Remove the front cover of the projector and check if all wire units at the left bottom of
the lens holder are connected.
Disconnected wire unit, of the lens
zoom/shift signals, from the Signal
Backplane. Remove the front cover and front dust fi lter from the projector and check if the wire unit
(reference 4 image 4-19) is inserted in the Signal Backplane (white plug behind blue
wires).
Malfunction Fan Control board. Replace the Fan Control board. See "Removing a board in the card cage", page 213.
Malfunction zoom motor of the lens. Use the local keypad to zoom the image on the screen. If unsuccessful, replace the
motorized lens.
Malfunction Signal Backplane (bad
connection). Replace the Signal Backplane. See "Replacement of the signal back plane", page 231.
Malfunction SMPS board which
supplies power to the lens. Replace the SMPS board. See "Replacement of the Switched Mode Power Supply",
page 281.
